METAL BEDSTEAD.

T0 all whom t may concern Be it known that l, RUBIN MAINKER, a citizen ot the United States, residing at Passaic, in the county of Passaic and State of New Jersey, have invented certain new and useful improvements in Metal Bedsteads; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to characters of reference marked thereon, which form a part of this specification.

This invention has reference, generally, to improvements pertaining to metal bedsteads; and, the present invention relates, more particularly, to a novel means and method ot connecting the tubular members of a metal bedstead in their assembled relation and more especially the bushing within the upper tubular frame portion of the bedstead, usually made of thin brass tubing, without the employment of the usual rivets.

rlhe invention has for its principal object, in the art pertaining to metal bedsteads, to positively unite by means of a tubular steel or similar bushing, the lower brasstube covered hollow or tubular bed-post, made or" steel tubing, or similar metal, to the upper trame-portion ot the bedstead, made of thin brass tubing, in a most efiicient and simple manner, without the use of the usual rivets, or without soldering, at the same time providing a method by means of which the various elements of the metal bedstead are readily and quickly united and at a considerable reduction in the cost of manufacture.

l'n metal bedsteads of the character herein set forth, the tubular posts are made from a rigid metal, such as steel tubing, covered with a casing of thin tubular brass, the upper frame-portion of the bedstead being made of thin tubular brass, the said upper frame-portion being united to the posts by means of tubular bushings, usually short pieces of steel tubing, the thin brass upper frame-portion heretofore having been secured to the portions of the bushings projecting above the ends ot the tubular posts by means of rivets, necessitating the drilling of holes for the rivets through the com- Speccation of Letters Patent.

bined thicknesses of the steel bushing and the tubular brass frame-portions.

With my present invention, I propose to first provide the steel bushing with two sets of vertically alined holes or perforations, the bushing being also preferably formed with an annular offset, with one set of said holes or perforations below said annular offset. The non-perforated tubular end-portions of the upper thin brass i'rameportion are slipped over the perforated upper parts of the bushings, slipping the end-portions of the upper thin brass frameportion down to the annular offsets of the bushings. Using the lower set of holes or perforations in the bushings as guides, by means of a punch, or other similar implement, the workman forces those portions of the upper thin frame-portion located over the upper set of holes or perforations into said holes or perforations in the tubular steel bushings, whereby the thin brass is perforated and inwardly extending retaining or fastening members are formed which are driven into said upper set of holes or perforations in the tubular steel bushings, and by means of which the parts are positively united, without the use of rivets or solder. Brass-covered tubular steel posts are now driven, from below, upon the projecting end-portions of the said bushings, until the brass casings or coverings of said steel posts butt upon the ends of the thin brass upper frame-portion. Suitable tubular ornaments are then slipped over the joints of the assembled parts, said ornaments being suitably secured in place, preferably, by means of pins which are driven into and are held by means of friction, in small holes or perfon rations variously located and formed in any suitable manner in the above-assembled parts.

lith the various objects of the present invention in View, the said invention consists, primarily, in the novel means and method of uniting the upper thin brass frame-portion of a metal bedstead to tubular steel or other suitable metal bushings, without the use of rivets or solder, and by means of such bushings uniting the upper thin brass trame-portion of the bedstead to the brass-incased tubular steel or other metal posts, substantially as set forth in the fol- The invention is illustrated in the accompanying drawings, in which Figure 1 is a face view of one of the'end trame-sectionsy of a metal bedstead, the upp'er'thin brass frame-portion thereof andthe tubular posts being united according tothe Vprinciples of the present invention. Fig. 2

is a detail transverse section, on an enlarged scale, of one or" the tubular bushings, and portions oit the upper thin brass frame-portion and the incased tubular post, united in the manner of the present invention.

Similar characters of reference are employed in the above described views, to indicate corresponding parts.

Referring now to the said drawings, the reference-characters 2, 2, indicate the thin brass tubular end-members of 'the upper frame-portion 1 of any one of the end trame-sections of a 'metal bedstead; 3, indicates the tubular metal bushing, usually a piece of steel tubing; and 1- indicates the tubular oosts also usuall made of steel tub- Y l a ing, and incased by thin brass tubino, as 5.

As shown in Fig. 2 of the drawings, the bushing 3 is made with an annular shoulder or offset, as 6, so that the maximum diameter of the lower reduced portion of said sleeve is approximately equal to the minimum or internal diameter of the tubular post 1-, the maximum diameter of said post being equal, or approximately so, to the maximum diameterof the larger upper portion of the said bushing 3. The said bushing 3 is also provided in its upper enlarged portion, at points near the said annular shoulder or otlset 6, with a series of holes or perforations 7, and in vertical alinement with the said holes or perforations 7, the said reduced portion of the bushing 3 is provided at points 'near the said annular shoulder or odset. 6 with another series of holes or perforations 8, the said latter series of holes or perfo-rations serving merely as a guidingmeans torthe purposes hereinabove stated.

In practice, the bushings 3 are inserted in the lower open ends of the thin brass endmembers 2, 2, of the frame-portion 1, to the'position indicated in said Fig. 2. By means of a punch or other suitable tool, using the holes or perforations S as a guiding means, the thin metal portions which are located over the holes or perforations 7, are forced in'inward directions into the said holes or perforations 7, so as to form eyeletlilre holding members or elements, as 9, which are forced into tight holding engagement with the metal portions which surround said holes or pertorations 7, and 1 whereby, as will be clearly evident, the bushings 3 and the thin tubular brass end-meml ers 2 are positively united and rigidly connected. The brass-incased posts et are now driven upon the vprojecting reduced portions or" the bushings 3, until the marginal edgeportions 10 ot the thin brass-casings are brought directly against the 'marginal edgeportions 11 of the thin brass tubular endineinbers '2 of the trame-portion 1. Holes or perfo-rations 12 Vand 13 vare now drilled in the assembled parts, and an ornamental sleeve 14 is slipped over the 'joint :termed by the abutting ends of the tubular brass members 2 and 5, the said sleeve 14 being provided with holes or perforations 15 and 16 which are brought intoregistration with the previously mentioned holes or perforations 12 and 13. Suitable holding or retaining pins 17 and 18 arenow rmly driven into the registering holes 12 and 15, and 13 and 16, whereby the sleeve '14 is securely held in place, as'will be'clearly evident from an Ainspection of said 'Fig'. 2 of the drawings.

From the foregoing description of my present invention, and from an inspection or said Fig. 2 of the drawings, it will be clearly seen, that the'various parts are easily and qiiickly,'brougl1t into their assembled and positively united relation, and especially are'the thin'tubular brass end-inembers 'of the upper frame portion securely and positively Vunit-ed to the steel bushings without'the use of rivets or solder,'as heretofore, so that thereby the parts are more 'quickly united, and the cost ofthe 'manufacture greatly reduced,`be'cause of the uncertain operation of inserting a clenching or riveting tool within the assembled tubular members is clearly avoided.

Of course it will be understood, that in lieu of the series of holes or pertorations 8 in the reduced portions of the bushings 3, other suitable guiding means may be employed in connection'with the said reduced portions for readily inding the brass covered holes or perforations 7, prior to the punching operations for Aforcing the brass parts of the end-members 2 into the said holes or perforations 7. am aware, therefore, that some changes may be made in the arrangementsl and combinations of the various devices and parts, as well as in the details of the construction of the same, without departing from the scope of the present invention as described in the said specilication, andas defined in the clauses of the claim which are appended to the said specitication. Hence, do not limit my present invention 'to the exact arrangements and Loeaies combinations of the various devices and parts as described in the said specification, nor do l confine myself to the exact details of the construction of the said parts as illustrat-ed in the accompanying drawings.
